Abstract: Here, operation for 3D beam forming is disclosed. UE, receiving reference signals from one or more base stations (eNBs), may report feedback information comprising precoding matrix information to the one or more eNBs. The precoding matrix information indicates a first type precoding matrix for a horizontal direction and a second type precoding matrix for a vertical direction. eNBs may transmit signals, which are precoded based on a third type precoding matrix for beam forming both on the horizontal direction and the vertical direction.

Abstract: A method performed by a user equipment (UE) that operates according to a first indicator and a second indicator is provided. When the UE is in a radio resource control (RRC) connected state with a first communication system and is in a state of idle mode with a second communication system, the UE receives a first message including the first indicator and the second indicator from the first communication system. The first indicator instructs the UE to perform association processes with a base station of the second communication system. The second indicator instructs the UE to operate in a power saving mode with the base station of the second communication system. After the UE performs the association processes, the UE switches to an RRC-idle mode state with the first communication system and enters the power saving mode from the idle mode with the second communication system.

Abstract: The present invention relates to radio communications between a terminal, a radio node and a core network in a radio communication system. A radio node, which can form a radio link to a terminal through a first radio interface by a first radio protocol and a second radio interface by a second radio protocol, may transmit, to the terminal, function structure type information about a mobility management-related function which can be performed through the first radio interface by the first radio protocol, form a radio link to the terminal through the second radio interface by the second radio protocol, establish a connection between the terminal and a core network by a non-access stratum (NAS) protocol if the terminal requests a connection between the terminal and the core network through the second radio interface, release the radio link, and perform the mobility management-related function through the second radio interface by communicating with the terminal.

Abstract: The present invention relates to a wireless access system, and provides a method of transmitting and receiving cell information by using a synchronization signal in a small-cell layout environment and a device supporting the same. A method of transmitting cell information in a wireless access system as an embodiment of the present invention may include the steps of: configuring one or more pieces of cell information by means of a base station; configuring a downlink synchronization signal including one or more pieces of cell information by means of the base station; and broadcasting the downlink synchronization signal by means of the base station. In this case, the cell information is configured to be information different from the downlink synchronization information configured based on the downlink synchronization signal.
